JEREMIAH C. LAUTENBACHER AND ALBERT GEARY, OF SCHUYLKILL HAVEN, PENNSYLVANIA.

COVER-RETAINER FOR RECEP'IACLES.

To all ac/1.0m it may concern:

Be it known that we, JEREMIAH C. LAU- TENBACHISR and ALBERT GEARY, citizens of the United States, residing at Schuylkill Haven, in the county of Schuylkill, State of lei'insylvania, have invented certain new and useful Improvements in Cover-Retainers for Receptacles, of which the following is a description, reference being had to the accompanying drawing and to the figures of refercnce marked thereon.

The invention relates to new and useful improvements in cover retainers for receptacles, and more particularly to a locking device which may be used for positively securing the cover to a can for milk or the like.

An object of the invention is to provide a locking device for the cover which will positively hold the cover on the receptacle, which locking device is so constructed that it may be readily manipulated for releasing the cover when desired.

A further object of the invention is to provide a construction of the above character wherein the cover is formed with a reinforced section, which supports the looking means for the cover and forms a rigid member through which the pressure or force of the locking means operates to hold the cover in place on the receptacle.

These and other objects will in part be obvious, and will in part be hereinafter more fully disclosed.

In the drawings, which show by way of illustration one embodiment of the invention, Figure 1 is a vertical sectional view through the upper part of a receptacle having our improved cover retaining means applied thereto; Fig. 2 is a detail in side elevation showing the locking means in position for releasing the cover; Fig. 3 is a plan view showing the locking fingers expanded to locking position; Fig. at is a detail in plan showing the locking nut for holding the cover on the receptacle.

In the drawings, .we have shown a receptacle 1, which is formed with a contracted neck 2, which is substantially cylindrical in cross section. The mouth of the receptacle is closed by a cover 8. This cover is preferably formed with a downwardly projecting por tion -'1-, which seats inside of the neck of the receptacle, and is also formed with a shoul- Specification of Letters Patent.

der 5, which rests on the upper edge of the neck of the receptacle. The cover centrally thereof is formed with a reinforcing section 6. This reinforcing section 6 is soldered to the cover and is formed so as to extend well out from the center of the cover. The reinforcing section is of substantial thickness so when pressure is brought to bear on this reinforcing section the shoulder 5 will be firmly held against the upper edge of the neck of the receptacle.

Threaded into the reinforcing section and extending through the cover is a supporting sleeve 7, through which extends a rod 8. The sleeve 7 is slotted as at 9, and is provided with projecting ears 10, to which is pivoted a locking finger 11. This locking finger extends downwardly and is curved outwardly as at 12. There are three locking fingers, as shown in the drawings, each of which is similar in construction. The lower end of the sleeve 7 is formed with an enlarged section 18. The rod 8 has a camshaped member 14: threaded thereon. This member is cone shaped and is adapted to engage the inner faces of the three retaining or locking fingers 12. Then the rod is lifted or forced in an upward direction, the cone pressing against the fingers will force the same outward into contact with the wall of the receptacle. These looking or retaining fingers are so disposed as to engage the receptacle at a point beneath the shoulder 15, so that when said fingers are forced positively into engagement with this part of the receptacle, said cover will be locked firmly on the neck of the receptacle. Each of the fingers is formed with a reinforcing extension 16, as clearly shown in the drawings.

The rod 8 extends above the reinforcing section 6 and is threaded to receive a locking nut 17. A locking hand nut 18 or threaded sleeve operated by a hand wheel 19 is also threaded onto a rod and serves to lock the rod from movement, and the nut 17 from turning on the rod when the cover is to be held on the receptacle. The locking nut 17 is formed with apertures 20 in the upper face thereof, into which may be inserted a spanner wrench for releasing the same if found necessary.

In the operation of our device, the hand nut 19 is moved up on the threaded rod 8, after which the locking nut 17 is also turned upivard on the rod, and then the rod may be forced downward through the sleeve 7 so as to bring the locking cone to the dotted line position in Fig. 1, and the locking fingers will drop by gravity against the surface of the cone so that the cover may be readily removed 1" om the receptacle, as the outer ends of the locking lingers, when in the position shovvn in the dotted lines,1naybereadily Withd 'aivn through the mouth of the receptacle. "il hen it is desired to lock the cover to the receptacle, the rod 8 is raised, the nut 17, turned dovrn n the rod until the same firmly seats against the hub of the reinforcing section 6, after vhich the hand nut is turned down against the nut 1?. By the use of these two locking nuts, one may he used to secure the other, and the rod from movement without requiring the same to be tightly set, and, therefore, the same may be readily released. This reinforcing section 6 not only serves as a means for reinforcing the cover, and distributing the pressure ivnieh holds the cover -:i\ .ted, but also serves as a rigid member for seating the SltzGY and rod which forms an element of our improved locking machines.

It is obvious that minor changes in the details of construction and the ar 'angement of parts may be made Without departing from the spirit of the invention, as set forth in the appended. claims.

Having thus described our invention, What we claim is:

1. The combination of a receptacle, a cover therefor, and means for loc ting said cover on said receptacle, including a sleeve carried by and depending from said cover, locking lingers pivotally carried by said sleeve, a rod movable through said sleeve, and having means for engaging said fingers for forcing the same into contact with the receptace,

and means for holding said rod from movement.

2. The combination of a receptacle, a. cover therefor, and means for looking said cover on said receptacle, including a reinforcing section mounted on the cover and secured thereto, said section extending outwardly from the center of the cover, sleeve threaded into said reinforcing section, locking ingers pivotally carried by said sleeve, a rod extending through said sleeve, a cam carried by the rod for engaging the lingers for forein g the same into contact with the receptacle, when said rod is raised, and means engaging said i'iinii'n'cing section for holding the rod raised.

3. The combination of receptacle, a cover therefor, and 11 cans for locking said cover on said receptacle, including a reinforcing see tion mounted on the cover and secured thereto, said section extending outwardly from the center of the cover, a sleeve threaded into said reinforcing section, locking lingers pivotally carr'ed by said sleeve, :1 rod extending th ough said sleeve, a 'am carried by the rod for engaging the fingers for forcing the same into contact with the 'eceptacle, when said rod is raised, and means engaging said reinforcing section for holding the rod 'aised, said means including a nut threaded onto said rod adapted to bear against said reinforcing section, and a. hand nut threaded on said rod and adapted to bear against said first named retaining nut.

In testimony uhereof, vve atlix our signatures, in the presence of tWO Witnesses.
